Question

tan A + tan B/cos A + cos B
= tan A×tan B​

Answer 1

Answer:

tan A +tan B/cos A+cos B numerator can be written in terms of sin and cos i.e

(sin A/cos A)+ (sin B/cosB ) /cos A+cos B

(sin A cos B +cos A sinB)/ cos A cos B

Step-by-step explanation:

sin Acos B/cos Acos B + cos A sin B/cosAcosB =sinA/cosA+sin B/cos B (cos B and cos A cancelled) and the answer will be tan A+tan B @@ i think it is the answer
